Picked up the HoMM5 during the sale, and all was going well after install. Launched Tribes of the East directly after install (when it lets you pick which HoMM5 game to launch immediately) and got in, made profile, and ran the first 2 campaigns just fine. However, once I exited the program, every time I tried to launch the program after the initial time it kept crashing at the main menu with an "Appcrash" error. So, I uninstalled/reinstalled and again- first time in everything went fine and smooth, got through a few scenarios, but once I exited the program any time I tried to launch the game after got the same stupid crash and error. I know it will run on my pc else I wouldn't have been able to play immediately after install, but I can't ever get it to run after that initial time (both the original HoMM5 and the Hammers of Fate xpac are running with no errors whatsoever, no matter how many times I exit/start the programs so the error seems exclusive the the Tribes of the East xpac)

If anyone has any ideas it would be appreciated, I have run file checks and anti virus and they all check out, but something is going wrong and I am stumped, so if anyone knows how I might resolve this I would really like to know.

Thanks
